Benefits and product highlights

One of the main strengths of the Devaux Terrestrial Flies JBF 03 lies in their ability to fool the most suspicious fish thanks to an ultra-realistic imitation.

Usage tips and recommended rigs

To exploit the full potential of the Terrestrial Flies JBF 03, favor a fine fluorocarbon tippet to allow a natural drift of the fly. This fly is ideally fished as a lightly sunk pattern along the margin, or sight-fished when fish are active on the surface. Pairing with a subtle tippet and a floating line will increase your chances of takes. It is recommended to place the fly near overhanging vegetation, shaded areas or banks with cover, spots frequented by terrestrial insects that have fallen into the water. Adjust the size and length of your leader according to water clarity and fish wariness.
